Worked on stabilizing the Home page interaction within the callstack-internal/Expensify-App repository by addressing navigation issues related to the Begin button. Focused on front end development using React and React Native, the approach involved reverting the Begin button’s navigation behavior to its previous, more reliable state and removing conditional logic based on report IDs. This simplification reduced the risk of navigation regressions and improved maintainability of the handler function. JavaScript and TypeScript were used to validate and streamline core navigation paths, ensuring that user interactions remained consistent and predictable while minimizing complexity in the application’s navigation logic.
